However, when you call `translate` from controller (e.g.
redirect_to path, notice: t(".done")) this setting has no effect. This is because
AbstractController::Translation#translate calls I18n.translate directly, and doesn't go through TranslationHelper
Yes, obviously the config option is scoped to "action_view" but still I found it pretty surprising.
I wanted raise behaviour by default in controllers to, so I added this to ApplicationController:
def translate(key, options={})
super(key, options.reverse_merge(raise: ActionView::Base.raise_on_missing_translations))
end
alias :t :translate
It'd be great though to have a universal raise_on_missing_translations option in Rails.
